Espruino build for nRF52832 board with external low-frequency 32678 kHz crystal

But from my current tries with my Holyiot YJ-17095 board, it seems the Espruino version consumes about 45uA so about 5 to 6 times more than the beacon version in C

It seems something was wrong with my preliminary tests on the Holyiot YJ-17095 board since today I measured an average power consumption on the Puck.js acting as a beacon of only 6.30uA @ 3V (see this post on the forum).
